Green Supplier Limited supplied gas and electricity to around 255,000 domestic customers and a small number of non-domestic customers before it ceased trading last week.

Outstanding credit balances, including money owed to both existing and former domestic customers of Green Supplier Limited will also be honoured.

Domestic customers will also be protected by the energy price cap with their new supplier.

For existing Green Supplier Limited customers, energy supplies will continue as normal as they switch over to Shell Energy on 27 September 2021.

Customers of Green Supplier Limited will be contacted over the coming days about the changes. If customers wish to switch supplier, they can shop around but are advised to wait until the transfer has been completed. Customers will not be charged exit fees if they decide to switch to another supplier.

Neil Lawrence, Ofgem’s director of retail, said: “I am pleased to announce we have appointed Shell Energy for the customers of Green Supplier Limited. We understand that this news may be unsettling for customers, however they do not need to worry. Their energy supply will continue as normal, and customer credit balances will be honoured.

“Shell Energy will be in contact with customers over the coming days with further information. Once the transfer has been completed, customers can switch if they wish to.”
